bin/magento module:enable Elgentos_OhDearChecks

Available Checks

Sansec Shield Security Check

This check verifies that the Sansec Shield security extension is properly installed, enabled, and configured:

• Module Installation: Checks if the Sansec_Shield module is installed
• Module Enablement: Verifies the module is enabled via sansec_shield/general/enabled configuration
• License Configuration: Ensures a license key is configured via sansec_shield/general/license_key

Check Results:

• ✅ OK: Module is installed, enabled, and has a license key configured
• ⚠️ WARNING: Module is installed and enabled but license key is missing
• ❌ FAILED: Module is not installed or not enabled

Indexer Backlog Check

This check monitors the backlog size for all scheduled indexers in your Magento store:

• Backlog Monitoring: Tracks the number of pending items for each scheduled indexer
• Status Tracking: Reports the current status of each indexer

Check Results:

• ✅ OK: All indexers are up to date or have minimal backlog (< 1,000 items)
• ⚠️ WARNING: High backlog detected (1,000 - 9,999 items)
• ❌ FAILED: Critical backlog detected (≥ 10,000 items)

Metadata Includes:

• Backlog size per indexer
• Maximum backlog across all indexers
• Number of indexers with backlog

HTTP Cache Hosts Check

This check verifies that HTTP cache hosts (Varnish) are properly configured for cache clearing:

• Configuration Check: Verifies that http_cache_hosts is configured in env.php
• Validation: Ensures at least one host is configured with both host and port parameters

Check Results:

• ✅ OK: HTTP cache hosts are properly configured
• ❌ FAILED: HTTP cache hosts are not configured or misconfigured

Metadata Includes:

• Configuration status
• Number of configured hosts
• List of configured hosts (without sensitive details)

Example Configuration in env.php:

'http_cache_hosts' => [
    [
        'host' => '127.0.0.1',
        'port' => '6081'
    ]
]

Configuration

You can disable any check by adding configuration to your env.php:

'ohdear' => [
    'Elgentos\\OhDearChecks\\Checks\\SansecShield' => [
        'enabled' => false
    ],
    'Elgentos\\OhDearChecks\\Checks\\IndexerBacklog' => [
        'enabled' => false,
        // Optional: customize which indexers to check
        'indexer_ids' => [
            'catalog_product_price',
            'catalog_category_product',
            'catalogsearch_fulltext',
            // ... add or remove indexer IDs as needed
        ],
        // Optional: global default thresholds (used when no per-indexer threshold is set)
        'warning_threshold' => 1000,
        'critical_threshold' => 10000,
        // Optional: per-indexer thresholds (override global defaults)
        'thresholds' => [
            'catalog_product_price' => [
                'warning' => 500,
                'critical' => 5000
            ],
            'catalogsearch_fulltext' => [
                'warning' => 2000,
                'critical' => 15000
            ],
            // ... configure thresholds for specific indexers
        ]
    ],
    'Elgentos\\OhDearChecks\\Checks\\HttpCacheHosts' => [
        'enabled' => false
    ]
]

Indexer Backlog Configuration Options

• indexer_ids (array): List of indexer IDs to monitor. If not specified, a default list of 10 common indexers is used.
• warning_threshold (int): Global warning threshold. Default: 1,000 items. Used when no per-indexer threshold is configured.
• critical_threshold (int): Global critical threshold. Default: 10,000 items. Used when no per-indexer threshold is configured.
• thresholds (array): Per-indexer threshold configuration. Each indexer can have its own warning and critical values that override the global defaults.

Priority Order:

1. Per-indexer threshold (if configured)
2. Global threshold (if configured)
3. Default threshold (1,000 for warning, 10,000 for critical)
